There is already a CNAME Record entry for this host in this zone.

I'm trying to change a CNAME record to an A record, but after deleting the cname record i get "There is already a CNAME Record entry for this host in this zone." when trying to add the A record. I have checked the zone file & there is no CNAME in it, so i guess ispconfig has a record of it elsewhere...

I have manually edited the zone file for the moment, but I wondered if any of you wonderfully experienced, and fantastically skilled people had any better (more elegant) ideas
